CVs can go from 1% to 100% piece-type density. It is hard to imagine
over 100% without double occupancy. There should be better example of high 50%
than Dave's Sample Game, which is 2/4:

Battle Chieftain, a playable cv, is not the only one exhibiting 1%,
http://www.chessvariants.org/large.dir/contest84/battlechieftan.html,
which 1/84 is there. The Druids of Hatch's Fantasy Grand are 20% if both sides have the same mix, each piece-type one only, so keeping rather typical 40% piece density 10x10:
http://www.chessvariants.org/large.dir/druid.html. Just remove Pawns and have no doubled pieces to get high piece-type density, but that aesthetic seems to be avoided. Some other famous ''tens,'' that is cvs of approximately ten percent piece-type density will follow.
Now one example is year 1999 contest winner Vyremorn,
